I would like to be able to trigger re-rendering of a single feature after a user has clicked on it. (I can catch the click and update the metadata that feeds the styling function, but I am then forced to re-render the entire layer to get the updated styling to show:
kmlSource.dispatchChangeEvent();
Performance is horrible redrawing a an entire large layer when just one feature's style has changed. Is there any way I can redraw just one feature?
Even if the rendering wasn't perfect (for example the redrawn feature was on top) that would be fine.
I note this older question on the previous version of openlayers, but I can't find anything addressing the issue on OpenLayers 3.

From the sounds of things I'd suggest trying the
changed()function on the feature after updating the styling. This seems to work when I updated the scale of the style for a feature. See the feature changed documentation
